One rectifier tube or 15 diodes - take your pick! The first company I worked for made dielectric preheaters with the largest production model putting out 15 KW. It was a rather simple oscillator with a Eimac triode. https://www.g8wrb.co.uk/data/Eimac/3CX15000A3.pdf The capacitors and diodes were made in house. They weren't something you could pick up at RadioShack. I don't remember how many diodes were chained but it was more than 15. They were soldered in a jig and then the whole assembly was potted into a brick about 12" long with lugs on both ends. The capacitors were fabricated from aluminum and RTV. The coils were constructed from 1" wide copper strips. The whole oscillator assembly looked very industrial rather than the simple circuit it was.
